[0029] The card dispenser is the prior art disclosed and can be directly used.

[0030] In a preferred embodiment of the utility model, the position of the bottom surface of the supporting base 102 is provided with an antiskid pad 103.

[0031] The antiskid pad can make the supporting base and the table top adhere more stably.

[0032] In a preferred embodiment of the utility model, the position of the top surface of the supporting base 102 located at the outer ring is provided with an auxiliary protection plate 201.

[0033] The auxiliary protection plate can effectively protect the rotation of the inner side synchronous belt and cut off the synchronous belt from the outside.

[0034] In a preferred embodiment of the utility model, the position of the surface of the supporting base 102 close to the top is provided with a stepped surface 202, and the position of the bottom surface of the rotating card dispenser body 101 is provided with an extension ring 203, and during installation, the extension ring 203 matches the stepped surface 202.

[0035] The stepped surface and the extension ring can make the connecting position of the supporting base and the rotating card dispenser body more beautiful, and impurities are not easy to enter, indirectly protecting the operation of the inner pulley and the synchronous belt and prolonging the service life.

[0036] In order to ensure the accuracy of the accurate dealing position, the rotating motor must be opened, which brings the following problems;

[0037] 1) The motor stops at the moment, the motor coil generates a back electromotive force, and the reverse impact current is formed. Due to the excessive reverse impact current, the motor impact vibration is caused, and the vibration is finally transmitted to the base, resulting in insufficient friction of the base anti-skid pad and rotating displacement.

[0038] 2) If the working voltage of the motor is reduced, the reverse impact current can be reduced, but the motor efficiency is low and the motor torque is reduced. How to effectively reduce the reverse impact current and reduce the rotating impact of the base while ensuring the power of the motor becomes a technical bottleneck in the industry. The commonly used motor control circuit diagram and working principle are shown in the attached Figure 8 ;

[0039] The motor is reversed: the driver loads the motor with a reverse voltage.

[0040] The attached Figure 9 ; At the moment when the motor stops, A and B are short-circuited, the back electromotive force E of the motor coil generates a reverse impact current, the motor driving integrated block AB is short-circuited, the motor coil internal resistance R0, the reverse impact current E / R0, the reverse impact current, brings a large rotating impact to the mechanism, and the vibration of the motor is transmitted to the base of the card dealer, causing the base to be unstable.

[0041] Through a new type of control circuit, the power of the motor is ensured, the reverse impact current generated at the moment when the motor stops is effectively reduced, the vibration impact of the motor on the base is reduced, and the equipment runs smoothly.

[0042] According to the circuit diagram of Figure 5 :

[0043] The motor is reversed: the driver loads the motor with a reverse voltage.

[0044] Q1 is turned on, Q2 is turned off, R1 is short-circuited, and R1 does not work.

[0045] According to the circuit diagram of Figure 6 :

[0046] The motor is reversed: the driver loads the motor with a reverse voltage.

[0047] Q1 is turned off, Q2 is turned on, R1 is short-circuited, and R1 does not work.

[0048] According to the circuit diagram of Figure 7 :

[0049] The motor is stopped: at the moment when the motor stops, the back electromotive force E of the motor coil generates a reverse impact current.

[0050] This time: Q1 cut, Q2 cut, R1 participate in shunt;

[0051] Motor coil resistance R0, shunt resistance R1, AB end short circuit;

[0052] Reverse impact current ;

[0053] Thus reduce the reverse impact current of motor, reduce the vibration of motor stop moment, thereby reducing the vibration of the base of the card dispenser, improve the stability of the base.

[0054] The traditional motor will form a reverse current when stopping, the coil forms a current to prevent the motor from running due to inertia, and acts as a brake, but due to the excessive reverse current, a large rotating impact is brought to the mechanism, and in the device, R1 is connected into the circuit, so that the resistance is increased, thereby reducing the brake current when the motor stops, and the purpose of reducing the rotating vibration of the motor is achieved.

[0055] The utility uses a triode control, and similarly, MOS tubes, relays and other electronic switches are considered as equivalent circuits.

[0056] Through the utility, the overall operation stability of the card dispenser is effectively improved, which is one of the important indicators of the poker machine, so that a better entertainment experience is obtained.
